2 cards from this section. Quick, good the night before a test.
What is shear modulus?
Think about material stiffness when a sideways force is applied.
Define shearing stress and shearing strain.
Connections to forces and dimensions can guide your definitions.
What does shear modulus measure?
Consider the forces that act parallel to the surface.
True or False: Shear modulus is greater than Young's modulus for most materials.
Think about the context of tensile vs. shear forces.
A metal rod with a radius of 5 mm and length of 1 m is subjected to a shear stress of 20 MPa. Calculate the displacement of the rod if its shear modulus is 80 GPa.
Use the formula related to shear strain and modulus for calculation.
Discuss the implications of a low shear modulus in a material used for earthquake-proof buildings.
Relate the concept to material selection in flexible structures.
